Multi-temperature primary air setup revealed the coolest peak bed temperature. Incineration is widely applied in municipal solid waste treatment and energy recovery, especially in China.

What are the main waste-to-energy technologies?

In this chapter, the main waste-to-energy (WtE) technologies are discussed along with the air emissions resulting from WtE plants. There are five main WtE processes: incineration, gasification, pyrolysis, anaerobic digestion, and torrefaction (or carbonization) (Gumisiriza et al. 2017; Badgett and Milbrandt 2020).

How is Air added during waste combustion?

During waste combustion, air is typically added in two main stages: Primary air is generally taken from the waste bunker and supplied through the grate layer into the fuel bed, and secondary combustion air is supplied at high speeds over the grate layer.

What is a waste-to-energy process?

Incineration process is considered the earliest waste-to-energy technology. When compared to other WtE processes, it is known to deal with a wider range of wastes including medical wastes, polyvinyl chloride plastics (PVC), discarded equipment/sharps, etc. (Messerle et al. 2018).
